- Interpon powder coating in full RAL spectrum
- Exceptional wind pressure resistance for high-rises
- Heavy load capacity for double/triple glazing
- Precision corner crimping with acoustic seals
Aluminium-Timber Composite
Combines warm, natural solid timber interior frames with a rugged exterior powder-coated aluminium shield to guard against weathering.
- Architectural warmth inside with durable exterior
- Natural interior wood grain timber choices
- Eliminates external timber refinishing costs
- Superior thermal mass insulation properties
Advanced Insulated Glass Units
Architectural Glazing Solutions
Glass represents up to 80% of a window area. SAGA provides precision IGUs customized for acoustic reduction, solar control, and hurricane impact safety.
| Glazing Type | Glass Make-up & Specs | Key Performance Advantages | Recommended Application |
|---|---|---|---|
| Double Glazing (IGU) | 5mm + 12Ar + 5mm Low-E Glass | Reduces thermal conductivity, prevents interior condensation, improves energy efficiency | Standard residential builds, apartments & volume developments |
| Triple Glazing | 5mm + 9Ar + 4mm + 9Ar + 5mm Double Low-E | Ultra-low U-Values (down to 0.8 W/m²K), outstanding heat retention in freezing climates | Cold climate regions, Passive House designs, high-end estates |
| Laminated Acoustic Glass | 6.38mm – 12.38mm PVB / Acoustic Interlayer | Dampens low and high-frequency sound waves, increases forced-entry protection | Urban residential towers, main road frontage, hotel suites |
| Hurricane Impact Glass | 6mm Toughened + 1.52 SGP/PVB + 6mm Toughened | Resists large missile impact (TAS 201/203), withstands intense cyclic wind loads | Florida coastal zones, Caribbean islands, storm-prone regions |

Frequently Asked Questions
Custom Window Manufacturing FAQ
The total project cost depends on frame material choice (uPVC, thermally broken aluminium, or timber composite), overall frame dimensions, glass configuration (double glazed Low-E, acoustic laminated, or hurricane impact), surface finishes, and hardware selections. Contact our technical sales engineering team with your window schedule for an accurate quote.
Yes. All SAGA window systems feature thermal breaks or multi-chamber insulating uPVC profiles paired with warm-edge spacer bars, argon gas fill, and Low-E glass coatings to meet stringent local energy rating compliance (such as NCC H1 or Energy Star standards).
We offer extensive finishing options including classic architectural white, matte black, monument grey, anodized metallic finishes, realistic woodgrain foils for uPVC, and full RAL Interpon powder-coating choices for aluminium profiles.
All frames and glass units are wrapped with protective foam and film, fitted with heavy-duty corner protectors, and securely packed inside fully enclosed fumigated plywood crates equipped with forklift entry points to ensure zero damage during sea transportation.
